Are you bored after winning every conceivable restaurant award? We could nominate you for non-food awards -- surely there’s a Pulitzer Prize for menu writing.
Are you worried about jumping the shark? Because, hell, we’d try shark sausage if you were making it AND we wouldn’t bitch about how the place was better 10 years ago.
You’ve said, "It’s time to do something else.” That’s fine, but that “something else” could be, “I carve canoes out of trees by hand, that is, when I’m not serving the best damn hot dogs in the city”. Please reconsider the permanence of Hot Doug’s vacation, maybe take a few months off, do some soul-searching, see what non-Chiberian Winters are like, and come back fresh as an andouille sausage.
